Hi everybody,
I am using asp.net and sql server database to develop a website
I am using Windows NT integrated security instead of username and
password
in web.config i added the connection string as
<appSettings>

<add key="ConnectionString" value="workstation id=JABBAR;packet size=4096;user id=jabbar;integrated security=SSPI;data source=SERVER;persist security info=False;initial catalog=BRYGOS" />
</appSettings>

and also I added
<system.web>
<identity impersonate="true" />
</system.web>

but when i launch the web page i am getting error

Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.

can anybody suggest me exactly what to do
